POPSBirth of Radio Astronomy This now includes seeing some of it visually as "snow" on televisions. Yet with the new transition to digital tv coming next year (in the U.S. at least), I wonder if "snow" will be a thing of the past?

POPSDark Stars The study says that particles of dark matter may have interacted with each other, producing other particles that heated the collapsing clouds. The heat kept the clouds from shrinking enough to ignite nuclear fusion.

POPS2300 Year Old Model Airplane Did anyone actually build a large version of this thing? Well, no one could have come this close to the real shape of flight without working on a larger scale. This little wooden model could hardly exist unless someone had worked with large, light models, or even with man-carrying versions. Archaeologists have looked in vain for a prototype. A large model light enough to fly would be too delicate to stand the ravages of 2300 years. The original -- if it ever was -- has long since joined the desert dust. Whatever form this Egyptian airplane might have taken, it has long since returned to the world of dreams and imagination from which it first came.

POPSStar Explodes Halfway Across the Universe 7.5 billion light years...just crazy. Trivia Pop quiz: Anyone know off the top of your head what the previous 2.5 million light year record mentioned is? It's a backyard astronomy favorite, and yes, easily visible in moderately dark skies (in the Fall). Almost giveaway hint

POPSStellar Time Bomb - Tick, Tick If it’s a binary, then both stars are likely to end their lives as supernovae -- explosions that blast the stars to bits. Each will leave behind a neutron star or a black hole. A single star would probably explode, too, but it could form one of the most powerful blasts in the universe -- a gamma-ray burst.
